We swim with the friendliest giant mantas in the world, and go face to face with great white sharks. Read about our experiences, guest comments and more here at the Nautilus at Sea blog! Plus special editorials by Captain Mike.

Juan convinced me into jumping for the last dive of the day. TWO HAMMER HEAD SHARKS with in minutes of entering the water. Great way to end the day. Thanks to Norbert for the patience waiting for the HH show.
